 * Retrieves a number format for a given locale.
 *
 * Numbers are formatted using patterns, like `#,###.00`. For example, the pattern `#,###.00`
 * when used to format the number 12345.678 could result in "12'345,678". That would happen if the
 * grouping separator for your language is an apostrophe, and the decimal separator is a comma.
 *
 * <b>Important:</b> The characters `.` `,` `0` `#` (and others below) are special placeholders
 * that stand for the decimal separator, and so on, and are NOT real characters.
 * You must NOT "translate" the placeholders. For example, don't change `.` to `,` even though in
 * your language the decimal point is written with a comma. The symbols should be replaced by the
 * local equivalents, using the appropriate `NumberSymbol` for your language.
 *
 * Here are the special characters used in number patterns:
 *
 * | Symbol | Meaning |
 * |--------|---------|
 * | . | Replaced automatically by the character used for the decimal point. |
 * | , | Replaced by the "grouping" (thousands) separator. |
 * | 0 | Replaced by a digit (or zero if there aren't enough digits). |
 * | # | Replaced by a digit (or nothing if there aren't enough). |
 * | ¤ | Replaced by a currency symbol, such as $ or USD. |
 * | % | Marks a percent format. The % symbol may change position, but must be retained. |
 * | E | Marks a scientific format. The E symbol may change position, but must be retained. |
 * | ' | Special characters used as literal characters are quoted with ASCII single quotes. |

    The NgClass directive uses the custom change detection algorithm for its inputs. The custom
    algorithm is necessary since inputs are represented as complex object or arrays that need to be
    deeply-compared.
  
    This algorithm is perf-sensitive since NgClass is used very frequently and its poor performance
    might negatively impact runtime performance of the entire change detection cycle. The design of
    this algorithm is making sure that:
    - there is no unnecessary DOM manipulation (CSS classes are added / removed from the DOM only when
    needed), even if references to bound objects change;
    - there is no memory allocation if nothing changes (even relatively modest memory allocation
    during the change detection cycle can result in GC pauses for some of the CD cycles).
  
    The algorithm works by iterating over the set of bound classes, staring with [class] binding and
    then going over [ngClass] binding. For each CSS class name:
    - check if it was seen before (this information is tracked in the state map) and if its value
    changed;
    - mark it as "touched" - names that are not marked are not present in the latest set of binding
    and we can remove such class name from the internal data structures;
  
    After iteration over all the CSS class names we've got data structure with all the information
    necessary to synchronize changes to the DOM - it is enough to iterate over the state map, flush
    changes to the DOM and reset internal data structures so those are ready for the next change
    detection cycle.

/**
 * Instantiates a {@link /api/core/Component Component} type and inserts its Host View into the current View.
 * `NgComponentOutlet` provides a declarative approach for dynamic component creation.
 *
 * `NgComponentOutlet` requires a component type, if a falsy value is set the view will clear and
 * any existing component will be destroyed.
 *
 * @usageNotes
 *
 * ### Fine tune control
 *
 * You can control the component creation process by using the following optional attributes:
 *
 * * `ngComponentOutletInputs`: Optional component inputs object, which will be bind to the
 * component.
 *
 * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
 * the Component. Defaults to the injector of the current view container.
 *
 * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
 * section of the component, if it exists.
 *
 * * `ngComponentOutletNgModule`: Optional NgModule class reference to allow loading another
 * module dynamically, then loading a component from that module.
 *
 * * `ngComponentOutletNgModuleFactory`: Deprecated config option that allows providing optional
 * NgModule factory to allow loading another module dynamically, then loading a component from that
 * module. Use `ngComponentOutletNgModule` instead.
 *
 * ### Syntax
 *
 * Simple
 * ```html
 * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
 * ```
 *
 * With inputs
 * ```html
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   inputs: inputsExpression;">
 * </ng-container>
 * ```
 *
 * Customized injector/content
 * ```html
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   injector: injectorExpression;
 *                                   content: contentNodesExpression;">
 * </ng-container>
 * ```
 *
 * Customized NgModule reference
 * ```html
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   ngModule: ngModuleClass;">
 * </ng-container>
 * ```
 *
 * ### A simple example
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='SimpleExample'}
 *
 * A more complete example with additional options:
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='CompleteExample'}

/**
 * A [structural directive](guide/directives/structural-directives) that renders
 * a template for each item in a collection.
 * The directive is placed on an element, which becomes the parent
 * of the cloned templates.
 *
 * The `ngForOf` directive is generally used in the
 * [shorthand form](guide/directives/structural-directives#asterisk) `*ngFor`.
 * In this form, the template to be rendered for each iteration is the content
 * of an anchor element containing the directive.
 *
 * The following example shows the shorthand syntax with some options,
 * contained in an `<li>` element.
 *
 * ```html
 * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
 * ```
 *
 * The shorthand form expands into a long form that uses the `ngForOf` selector
 * on an `<ng-template>` element.
 * The content of the `<ng-template>` element is the `<li>` element that held the
 * short-form directive.
 *
 * Here is the expanded version of the short-form example.
 *
 * ```html
 * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
 *   <li>...</li>
 * </ng-template>
 * ```
 *
 * Angular automatically expands the shorthand syntax as it compiles the template.
 * The context for each embedded view is logically merged to the current component
 * context according to its lexical position.
 *
 * When using the shorthand syntax, Angular allows only [one structural directive
 * on an element](guide/directives/structural-directives#one-per-element).
 * If you want to iterate conditionally, for example,
 * put the `*ngIf` on a container element that wraps the `*ngFor` element.
 * For further discussion, see
 * [Structural Directives](guide/directives/structural-directives#one-per-element).
 *
 * @usageNotes
 *
 * ### Local variables
 *
 * `NgForOf` provides exported values that can be aliased to local variables.
 * For example:
 *
 *  ```html
 * <li *ngFor="let user of users; index as i; first as isFirst">
 *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
 * </li>
 * ```
 *
 * The following exported values can be aliased to local variables:
 *
 * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
 * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
 * more complex then a property access, for example when using the async pipe (`userStreams |
 * async`).
 * - `index: number`: The index of the current item in the iterable.
 * - `count: number`: The length of the iterable.
 * - `first: boolean`: True when the item is the first item in the iterable.
 * - `last: boolean`: True when the item is the last item in the iterable.
 * - `even: boolean`: True when the item has an even index in the iterable.
 * - `odd: boolean`: True when the item has an odd index in the iterable.
 *
 * ### Change propagation
 *
 * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
 *
 * * When an item is added, a new instance of the template is added to the DOM.
 * * When an item is removed, its template instance is removed from the DOM.
 * * When items are reordered, their respective templates are reordered in the DOM.
 *
 * Angular uses object identity to track insertions and deletions within the iterator and reproduce
 * those changes in the DOM. This has important implications for animations and any stateful
 * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
 * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
 * such as user input.
 * For more on animations, see [Transitions and Triggers](guide/animations/transition-and-triggers).
 *
 * The identities of elements in the iterator can change while the data does not.
 * This can happen, for example, if the iterator is produced from an RPC to the server, and that
 * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
 * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
 * elements were deleted and all new elements inserted).
 *
 * To avoid this expensive operation, you can customize the default tracking algorithm.
 * by supplying the `trackBy` option to `NgForOf`.
 * `trackBy` takes a function that has two arguments: `index` and `item`.
 * If `trackBy` is given, Angular tracks changes by the return value of the function.

/**
 * A structural directive that conditionally includes a template based on the value of

 * When the expression evaluates to true, Angular renders the template
 * provided in a `then` clause, and when  false or null,
 * Angular renders the template provided in an optional `else` clause. The default
 * template for the `else` clause is blank.
 *
 * A [shorthand form](guide/directives/structural-directives#asterisk) of the directive,
 * `*ngIf="condition"`, is generally used, provided
 * as an attribute of the anchor element for the inserted template.
 * Angular expands this into a more explicit version, in which the anchor element
 * is contained in an `<ng-template>` element.
 *
 * Simple form with shorthand syntax:
 *
 * ```html
 * <div *ngIf="condition">Content to render when condition is true.</div>
 * ```
 *
 * Simple form with expanded syntax:
 *
 * ```html
 * <ng-template [ngIf]="condition"><div>Content to render when condition is
 * true.</div></ng-template>
 * ```
 *
 * Form with an "else" block:
 *
 * ```html
 * <div *ngIf="condition; else elseBlock">Content to render when condition is true.</div>
 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
 * ```
 *
 * Shorthand form with "then" and "else" blocks:
 *
 * ```html
 * <div *ngIf="condition; then thenBlock else elseBlock"></div>
 * <ng-template #thenBlock>Content to render when condition is true.</ng-template>
 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
 * ```
 *
 * Form with storing the value locally:
 *
 * ```html
 * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
 * <ng-template #elseBlock>Content to render when value is null.</ng-template>
 * ```
 *
 * @usageNotes
 *
 * The `*ngIf` directive is most commonly used to conditionally show an inline template,
 * as seen in the following  example.
 * The default `else` template is blank.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
 *
 * ### Showing an alternative template using `else`
 *
 * To display a template when `expression` evaluates to false, use an `else` template
 * binding as shown in the following example.
 * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.
 * The template can be defined anywhere in the component view, but is typically placed right after
 * `ngIf` for readability.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfElse'}
 *
 * ### Using an external `then` template
 *
 * In the previous example, the then-clause template is specified inline, as the content of the
 * tag that contains the `ngIf` directive. You can also specify a template that is defined
 * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
 * change which template to use at runtime, as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
 *
 * ### Storing a conditional result in a variable
 *
 * You might want to show a set of properties from the same object. If you are waiting
 * for asynchronous data, the object can be undefined.
 * In this case, you can use `ngIf` and store the result of the condition in a local
 * variable as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfAs'}
 *
 * This code uses only one `AsyncPipe`, so only one subscription is created.
 * The conditional statement stores the result of `userStream|async` in the local variable `user`.
 * You can then bind the local `user` repeatedly.
 *
 * The conditional displays the data only if `userStream` returns a value,
 * so you don't need to use the
 * safe-navigation-operator (`?.`)
 * to guard against null values when accessing properties.
 * You can display an alternative template while waiting for the data.
 *
 * ### Shorthand syntax
 *
 * The shorthand syntax `*ngIf` expands into two separate template specifications
 * for the "then" and "else" clauses. For example, consider the following shorthand statement,
 * that is meant to show a loading page while waiting for data to be loaded.
 *
 * ```html
 * <div class="hero-list" *ngIf="heroes else loading">
 *  ...
 * </div>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * You can see that the "else" clause references the `<ng-template>`
 * with the `#loading` label, and the template for the "then" clause
 * is provided as the content of the anchor element.
 *
 * However, when Angular expands the shorthand syntax, it creates
 * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
 * The anchor element containing the template for the "then" clause becomes
 * the content of this unlabeled `<ng-template>` tag.
 *
 * ```html
 * <ng-template [ngIf]="heroes" [ngIfElse]="loading">
 *  <div class="hero-list">
 *   ...
 *  </div>
 * </ng-template>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * The presence of the implicit template object has implications for the nesting of
 * structural directives. For more on this subject, see
 * [Structural Directives](guide/directives/structural-directives#one-per-element).

 * ### Usage Examples
 *
 * The following example shows how to use more than one case to display the same view:
 *
 * ```html
 * <container-element [ngSwitch]="switch_expression">
 *   <!-- the same view can be shown in more than one case -->
 *   <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *   <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *   <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
 *   <!--default case when there are no matches -->
 *   <some-element *ngSwitchDefault>...</some-element>
 * </container-element>
 * ```
 *
 * The following example shows how cases can be nested:
 * ```html
 * <container-element [ngSwitch]="switch_expression">
 *       <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *       <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *       <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
 *       <ng-container *ngSwitchCase="match_expression_3">
 *         <!-- use a ng-container to group multiple root nodes -->
 *         <inner-element></inner-element>
 *         <inner-other-element></inner-other-element>
 *       </ng-container>
 *       <some-element *ngSwitchDefault>...</some-element>
 *     </container-element>
 * ```

/**

 * When the expressions match, the given `NgSwitchCase` template is rendered.
 * If multiple match expressions match the switch expression value, all of them are displayed.
 *
 * @usageNotes
 *
 * Within a switch container, `*ngSwitchCase` statements specify the match expressions
 * as attributes. Include `*ngSwitchDefault` as the final case.

 *
 * Each switch-case statement contains an in-line HTML template or template reference
 * that defines the subtree to be selected if the value of the match expression
 * matches the value of the switch expression.
 *
 * As of Angular v17 the NgSwitch directive uses strict equality comparison (`===`) instead of

/**
 * @ngModule CommonModule
 * @description
 *
 * Unwraps a value from an asynchronous primitive.
 *
 * The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has
 * emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
 * changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
 * potential memory leaks. When the reference of the expression changes, the `async` pipe
 * automatically unsubscribes from the old `Observable` or `Promise` and subscribes to the new one.
 *
 * @usageNotes
 *
 * ### Examples
 *
 * This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
 * promise.
 *
 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
 *
 * It's also possible to use `async` with Observables. The example below binds the `time` Observable
 * to the view. The Observable continuously updates the view with the current time.
 *
 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipeObservable'}

 * @description
 *
 * Formats a date value according to locale rules.
 *
 * `DatePipe` is executed only when it detects a pure change to the input value.
 * A pure change is either a change to a primitive input value
 * (such as `String`, `Number`, `Boolean`, or `Symbol`),
 * or a changed object reference (such as `Date`, `Array`, `Function`, or `Object`).
 *
 * Note that mutating a `Date` object does not cause the pipe to be rendered again.
 * To ensure that the pipe is executed, you must create a new `Date` object.
 *
 * Only the `en-US` locale data comes with Angular. To localize dates
 * in another language, you must import the corresponding locale data.
 * See the [I18n guide](guide/i18n/format-data-locale) for more information.
 *
 * The time zone of the formatted value can be specified either by passing it in as the second
 * parameter of the pipe, or by setting the default through the `DATE_PIPE_DEFAULT_OPTIONS`
 * injection token. The value that is passed in as the second parameter takes precedence over
 * the one defined using the injection token.
 *
 * @see {@link formatDate}

 * reformat the date on every change-detection cycle, treat the date as an immutable object
 * and change the reference when the pipe needs to run again.

 * ### Format examples
 *
 * These examples transform a date into various formats,
 * assuming that `dateObj` is a JavaScript `Date` object for
 * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
 * given in the local time for the `en-US` locale.
 *
 * ```
 * {{ dateObj | date }}               // output is 'Jun 15, 2015'
 * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
 * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
 * {{ dateObj | date:'mm:ss' }}       // output is '43:11'
 * {{ dateObj | date:"MMM dd, yyyy 'at' hh:mm a" }}  // output is 'Jun 15, 2015 at 09:43 PM'
 * ```
 *
 * ### Usage example
 *
 * The following component uses a date pipe to display the current date in different formats.
 *
 * ```angular-ts
 * @Component({
 *  selector: 'date-pipe',
 *  template: `<div>
 *    <p>Today is {{today | date}}</p>
 *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
 *    <p>The time is {{today | date:'h:mm a z'}}</p>
 *  </div>`
 * })
 * // Get the current date and time as a date-time value.
 * export class DatePipeComponent {
 *   today: number = Date.now();
 * }
 * ```

 * decimal point character, and other locale-specific configurations.
 *
 * @see {@link formatNumber}
 *
 * @usageNotes
 *
 * ### digitsInfo
 *
 * The value's decimal representation is specified by the `digitsInfo`
 * parameter, written in the following format:<br>
 *
 * ```
 * {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
 * ```
 *
 *  - `minIntegerDigits`:
 * The minimum number of integer digits before the decimal point.
 * Default is 1.
 *
 * - `minFractionDigits`:
 * The minimum number of digits after the decimal point.
 * Default is 0.
 *
 *  - `maxFractionDigits`:
 * The maximum number of digits after the decimal point.
 * Default is 3.
 *
 * If the formatted value is truncated it will be rounded using the "to-nearest" method:
 *
 * ```
 * {{3.6 | number: '1.0-0'}}
 * <!--will output '4'-->
 *
 * {{-3.6 | number:'1.0-0'}}
 * <!--will output '-4'-->
 * ```
 *
 * ### locale
 *
 * `locale` will format a value according to locale rules.
 * Locale determines group sizing and separator,
 * decimal point character, and other locale-specific configurations.
 *
 * When not supplied, uses the value of `LOCALE_ID`, which is `en-US` by default.
 *
 * See [Setting your app locale](guide/i18n/locale-id).
 *
 * ### Example
 *
 * The following code shows how the pipe transforms values
 * according to various format specifications,
 * where the caller's default locale is `en-US`.

/**
 * @ngModule CommonModule
 * @description
 *
 * Creates a new `Array` or `String` containing a subset (slice) of the elements.
 *
 * @usageNotes
 *
 * All behavior is based on the expected behavior of the JavaScript API `Array.prototype.slice()`
 * and `String.prototype.slice()`.
 *
 * When operating on an `Array`, the returned `Array` is always a copy even when all
 * the elements are being returned.
 *
 * When operating on a blank value, the pipe returns the blank value.
 *
 * ### List Example
 *
 * This `ngFor` example:
 *
 * {@example common/pipes/ts/slice_pipe.ts region='SlicePipe_list'}
 *
 * produces the following:
 *
 * ```html
 * <li>b</li>
